GENERAL DESCRIPTION Introduction
This manual provides the installation and operating instructions for the Garmin GTX 320 and the GTX 320A Transponders. Information pertaining to the maintenance, alignment, and procurement of replacement parts is found in the GTX 320 Maintenance Manual, P/N 190-00133-02 and the GTX 320A Maintenance Manual, P/N 190-00133-08. After installation of the GTX 320/ GTX 320A, FAA Form 337 must be completed by an appropriately certificated agency and ATC transponder tests required by 14 CFR, Part 91.413 must be completed to return the aircraft to service.

Equipment Description

The Garmin GTX 320/320A Transponder is a radio transmitter and receiver that operates on radar frequencies. Receiving ground radar interrogations at 1030 MHz, it transmits a coded response of pulses to ground-based radar on a frequency of 1090 MHz. As with other Mode A/Mode C transponders, the GTX 320/320A replies with any one of 4,096 codes, which differ in the position and number of pulses transmitted. By replying to ground transmissions, your GTX 320/320A enables ATC computers to display aircraft identification, altitude and ground speed on ATC radar screens. The GTX 320/320A is equipped with IDENT capability that activates the Special Position Identification Pulse (SPI) for approximately 20 seconds (18 seconds for the GTX 320A) identifying your transponder return from other aircraft on the controllers scope.

Installation Approval

The conditions and tests required for TSO approval of the GTX 320/320A Transponder and antenna are minimum performance standards. It is the responsibility of the installer to determine that the aircraft installation standards for a specific type or class of aircraft are in compliance with all applicable TSO requirements. The GTX 320/320A and antenna may be installed only if further evaluation by the applicant documents an acceptable installation and is approved by the administrator. For GTX 320/320A TSO compliance, see Appendix A. For antenna TSO compliance, refer to antenna manufacturers literature.
ATC Transponder Tests and Inspections
The ATC transponder tests required by 14 CFR, Part 91.413 may be conducted using a bench check or portable test equipment and must meet the requirements prescribed in Part 43 Appendix F. If portable test equipment with appropriate coupling to the aircraft antenna system is used, operate the test equipment for ATCRBS transponders at a nominal rate of 235 interrogations per second to avoid possible ATCRBS interference. An additional 3 dB loss is allowed to compensate for antenna coupling errors during receiver sensitivity measurements conducted in accordance with Part 43 Appendix F, Paragraph (c)(1) when using portable test equipment.

INSTALLATION OVERVIEW Introduction
This section provides the necessary information for installing the GTX 320/320A Transponders, and where required, optional accessories. Installation of the GTX 320/320A Transponder should comply with the aircraft Type Certificate (TC) or Supplemental Type Certificate (STC). Cabling will be fabricated by the installing agency to fit each particular aircraft. The guidance of FAA advisory circulars AC 43.13-1B and AC 43.13-2A, where applicable, may be found useful for accomplishing retro-fit installations that comply with FAA regulations. This section contains interconnect diagrams, mounting dimensions, and information pertaining to installation.
Unpacking and Inspecting Equipment
Carefully unpack the equipment and make a visual inspection of the unit for evidence of damage incurred during shipment. If the unit is damaged, notify the carrier and file a claim. To justify a claim, save the original shipping container and all packing materials. Do not return the unit to Garmin until the carrier has authorized the claim. Retain the original shipping containers for storage. If the original containers are not available, a separate cardboard container should be prepared that is large enough to accommodate sufficient packing material to prevent movement.

Antenna Installation

2.3.1 Location Considerations
A. The antenna (Garmin P/N 010-10160-00) should be well removed from any major protrusions, the engine(s), propeller(s), and antenna masts. It should also be as far removed as practical from landing gear doors, access doors, or other openings that could alter its radiation pattern. The antenna should be mounted on the underside of the aircraft and in a vertical position (relative to the position of the aircraft in level flight). Avoid mounting the antenna within three feet of the ADF sense antenna or any other communication antenna and six feet from the DME antenna. To prevent RF interference, the antenna must be mounted a minimum distance of three feet from the GTX 320/320A.
If the antenna is being installed on a composite aircraft, ground planes may be required. Conductive wire mesh, radials, or thin aluminum sheets embedded in the composite material provide the proper ground plane allowing the antenna pattern (gain) to be maximized for optimum transponder performance.
2.3.2 Antenna Installation
Install the antenna according to the antenna manufacturers instructions and FAA AC 43.13-2A.

Page 2-1 Rev M

2.3.3 Installation Approval Considerations for Pressurized Aircraft

Antenna and cable installations on pressurized cabin aircraft require FAA approved installation design and engineering substantiation data whenever such installations incorporate alteration (penetration) of the cabin pressure vessel by connector holes and/or mounting arrangements. For needed engineering support pertaining to the design and approval of such pressurized aircraft antenna installations, it is recommended that the installer proceed according to any of the following listed alternatives: 1. Obtain approved antenna installation design data from the aircraft manufacturer. 2. Obtain an FAA approved Supplemental Type Certificate (STC) pertaining to and valid for the subject antenna installation. 3. Contact the FAA Aircraft Certification Office in the appropriate Region and request identification of FAA Designated Engineering Representatives (DERs) who are authorized to prepare and approve the required antenna installation engineering data. 4. Obtain FAA Advisory Circular AC-183C and select (and contact) a DER from the roster of individuals identified there under. 5. Contact an aviation industry organization such as the Aircraft Electronics Association and request their assistance.

Page 2-2 Rev M

2.3.4 Antenna Cable Installation
When routing antenna cables, observe the following precautions: All cable routing should be kept as short as possible and as direct as possible. Avoid sharp bends. Avoid routing cables near power sources (e.g., 400 Hz generators, trim motors, etc.) or near power for fluorescent lighting. Avoid routing cable near ADF antenna cable (allow at least a 12-inch separation). The table below lists the recommended 50 ohm double shielded coax antenna cable vendor and the type to be used for specific lengths of cable. Adherence to this table will ensure that the coax installation will not exceed the maximum allowable 1.5 dB attenuation at the transmitter operating frequency of 1090 MHz.

With the intro of the GTX 327, Garmin revolutionizes a part of the panel that has been long overlooked. This fullfeatured, TSO certified transponder brings a unique level of functionality and utility to your airplane. Its solid state transmitter provides 200 watts nominal power output and eliminates the need for a cavity tube which will eventually fail and require expensive replacement. And since the GTX 327 design is 100% solid state there is no warm up time, lower power consumption and lower heat emission. All of which translates to a longer service life. Some of the GTX 327 biggest features are the easiest to see. Among them, the easy-riding DSTN Liquid Crystal Display which reverses yellow numbers out of black for optimal viewing. An innovative keypad makes entering a squawk code a snap. And a dedicated VFR button allows for quick and easy 1200/VFR squawking. The GTX 327 also offers two important timing functions. The first screen shows the current time and count up timer. The second indicates flight time and a count down timer. Together they represent a whole new standard in transponder utility.
